The term 'EGG TO BE FERTILIZED' can be summarized as the OVUM, which is a four-letter word. An OVUM is a female reproductive cell that must be fertilized by a male sperm cell in order for conception to occur. The OVUM is the largest cell in the human body and is released from the ovaries during ovulation. It is then transported through the fallopian tubes to the uterus, where it can be fertilized by a sperm cell. If fertilization does not occur, the OVUM will be expelled from the body during menstruation.
